8vo. pp. xiii, [1], 851. index. cloth (small stain on spine). Second Edition, Seventh Impression. "Security Analysis was first published in 1934 at the start of the Great Depression,while Graham was a lecturer at Columbia Business School. The book laid out the fundamental groundwork of value investing, which involves buying undervalued stocks with the potential to grow over time. At a time when the stock market was known to be a speculative vehicle, the notion of intrinsic value and margin of safety, which were first introduced in Security Analysis, paved the way for a fundamental analysis of stocks void of speculation." (Julia Kagan, Who Was Benjamin Graham) "Throughout his career, Graham had many notable disciples who went on to earn substantial success as investors, including Irving Kahn and Warren Buffett, who described Graham as the second most influential person in his life after his own father."
